Summary:                    Millions of "We're Zap/4-2, not", than crash
Description: 
I have an asterisk server with Digium TDM840 card. Sometimes I get millions
of messages per second like "We're Zap/4-2, not" or "We're Zap/4-2, not
(null)". Than asterisk crashes: asterisk[3634]: segfault at 92765b41 ip
b7dd644b sp b6d4fe14 error 4 in libc-2.3.3.so[b7d5a000+142000].
